1 Prtein Recvery System (PRS ) Intrductin A new generatin REDA Separatrs are cming int the market when milk is prcessed. The milk lss due t the discharge actin can be reduced clsed t zer with an imprtant design mdificatin jinted t a new sftware functin. The REDA upgraded its separatr wrking n existing advantaged recgnized design intrducing the fllwing mdificatin : Optimized sludge chamber (OSC ): The sludge chamber must be big enugh t cntain sludges separated frm skimmilk utlet (discs utlet diameter) ; in this manner sludges can be ejected with a lwer frequency Since each discharge means a skimmilk (prtein) lss, bigger is the chamber less are the discharges number and therefre the skimmilk (prtein) lss The sludge chamber must be nt t big because when separatr discharges it ejects the entire cntent f the chamber and nt nly the sludges (it means that the mst f the skimmilk(prtein) crssing thrugh the chamber is lst) : smaller is the chamber less is the prduct lst each discharge (prtein lss). Strnger and faster discharge (FDS ) When the sludge is high cncentraded int the sludge chamber, the ejectin (discharge) is mre critical : it is necessary washing chamber by sme liquid cntained int the chamber itself. It means t lse skimmilk (prtein) : it is as much as higher when the ejectin is nt perfect. The best ejectin needs t be fast and strng : nly in this way the quantity f skimmilk (prtein) lst tgether t the sludge can be reduced. REDA new generatin separatr intrduces a strnger and faster discharge because the bwl pens mre in a shrter time : the big effrt generated ver the mechanical drive can nw easily supprted by REDA Sft shaft system and by Freq-clutch system. Besides the abve ptimizatins REDA nw can ffer the PRS system that cuts clsed t zer the milk and prtein lss. page 1/6

2 Hw t save prtein ( Zer prtein lss) - PRS system The PRS system supprted by a sftware full cntrl prvides t empty the bwl by milk befre each discharge, but letting the pasteurizing unit wrking withut any prblem f prduct default. New generatin separatr with a OSC and FDS systems can be supplied tgether t the PRS system t cut the milk and prtein lss due t the separatr wrking. Cmpare t nrmal separatr perating int milk skimming r standardizing the gain is the fllwing: Type f machine : RE200T Feeding capacity 20,000 liters/hur Operating hurs/day 10 h/day Operating days/year 350 d/year Results Standard system PRS units Discharges per hur 3 1 numbers Vlume f discharge liters Milk lst/each discharge 5 0 liters Milk lst/day liters Milk lst/year liters Difference (milk saved) Standard system VS. PRS liters/year Water/each discharge liters Water/day 3 0,45 m 3 Water/years ,5 m 3 Standard system Difference VS. (water save) PRS 157,5 m 3 /year Sludge+effluents/discharge liters Sludge+effluents/day liters Sludge+effluents/year liters Difference Standard system VS. PRS liters/year page 2/6

3 Payback time REDA is intrducing int the market the new generatin separatr with OSD and FDS and in the next future all the centrifuges will be equipped with the abve systems. Fr abve reasn the nly extra cst fr prtein recvery system will be the PRS system that can be payback in a very shrt time (much less than ne year). Mrever the ttal discharge quantity f effluents and water cnsumptin decrease prprtinally allwing an extra gain. Cmpetitrs similar systems On the market there are ther systems t reduce the prtein lss. But the cst t intrduce the system is very high (mre r less ten times f PRS ) with the same r wrse result. Press infrmatin dne by cmpetitrs gives the gain cmpare t their nrmal system, but REDA nrmal system already gives advantages in the prtein saving cmpare t the cmpetitrs. Cnclusin Prtein lss due t centrifuge wrking was always neglected in the past, but nw the mre attentin t the increasing f plants efficiency fcalizes the attentin als in this field. Mrever REDA always lks at envirnment prblems ; less effluents, less water cnsumptin add a very high value at PRS system. The PRS system can be included int the fllwing applicatins : Milk skimming Milk standardizing Milk clarificatin Milk bactfugatin Fr any further infrmatin please cntact : page 3/6

4 Whey prcess : a new PRS applicatin In the whey prcess PRS system it can be intrduced but in the past it seemed there is n big advantage due t the lw value f the whey. But recently whey price raised a lt caused an earthquake in the wrld market. It has changed cmpletely the perspective because nw whey recvery is becming imprtant : the PRS can be set n whey skimming separatr with a shrt pay-back investment. Type f machine : RE150T Feeding capacity 20,000 liters/hur Operating hurs/day 10 h/day Operating days/year 350 d/year Results Standard system PRS units Discharges per hur 6 2 numbers Vlume f discharge liters Whey lst/each discharge 5 0 liters Whey lst/day liters Whey lst/year liters Whey pwder lst/year Kgs Whey pwder has a cst f 1,200 Eur per tns, but t calculate the mney saving fr a cheese factry we have t cnsider the price f whey t sell : it can reach 600 Eurs/tns Prfit 6,8 Tns 600 Eurs/Tns 4080 Eurs/year page 4/6

5 PRS installatin The PRS unit is pre-assembled n a skid : an extremely easy installatin gives als t the Operatr the capacity t cntrl and adjust the system fr the best prduct recvery. The system can be set n existing unit, but fr the best perfrming a separatr mdificatin shuld be set. PRS descriptin The PRS unit has the fllwing cmpnents : Pressurizing unit with balance water tank, high pressure pump, expansin tanks Brazed-heat exchanger fr temperature cntrl Pressure transmitters Temperature transmitters Inlet back-pressure valve page 5/6

6 Three-way pneumatic valve Slenid valves fr autmatin cntrl PLC supervisin t cntrl the system On the same skid it is assemblied als the water unit system (balance-tank, pump, filter). page 6/6
